Jquery ajax – Submitting a form with ajax to a new tab

I have a table with checkboxes on each row for different actions – one of them is print all, which generates a pdf.

Therefore I want to submit the form to a page that opens in a new tab. How can I achieve this?

var form = $("#formname");
var url = "url.php";
$.ajax({
    type: "POST",
    url: url,
    data: form.serialize(),
    success: function(data) {
        //Success
    }
});
